I would like to know if the following kind of database client exists: I need a 'select' query to be sent to say 10 db
serverssimultaneously in parallel (using threading), the results should be re-sorted and returned. For example I have a
query:'select * from table where parent_clname = 'parent' order by name limit 10'. Now this query has to be sent to 10
servers,and the maximum number of results would be 100. Now this 100 result set has to be re-sorted, out of which 90
hasto be discarded, and the 10 has to be returned.
Does such a solution exist now. To me this appears to be in entirety of what should constitute a database cluster.
Onlythe search needs to be done on all the servers simultaneously at the low level. Once you get the results, the
writingcan be determined by the upper level logic (which can even be in a scripting language). But the search across
manyservers has to be done using proper threading, and the re-sorting also needs to be done fast.
Thanks a lot in advance.
